Today is the 38th annual Earth Day, so in honor of the big event, I offer up some "green" links:
- EarthDay.gov  - the government's clearinghouse site for Earth Day info.
- Earth Day Network  - live coverage of Earth Day events around the world.
- Green Libraries  - if you're interested in ideas for your library, check out this site. You can find links to green libraries, and learn about how to make changes at your own library!
- History of Earth Day  - by the founder of Earth Day, Senator Gaylord Nelson.
- ToxTown  - from the U.S. National Library of Medicine, this site is designed for kids and teachers to help teach them about all of the potential toxic dangers in the home, workplace, and school (kind of scary!).
- Watching Earth from Space  - News.com has gathered this photo gallery from NASA. The images were all taken from space, looking back at Earth.
